The two Maslenica bridges not only connect two bodies of land, they are also a natural boundary between freshwater and seawater habitats. Strong currents, the result of changing tides, create tidewaters that flow in one direction over a six-hour period and then back again over another six-hour period. There is a 45-minute time slot for diving without strong currents when the tide and current change.
Dives can be from the shore or from a boat. It is highly recommendable that it be from shallow waters and planned ahead in view of current status. Diving in pairs is compulsory; the distance between divers should not exceed 5 m.
The mixture of fresh and sea water found here is an ideal habitat for numerous species – garfish, sea anemones, sponges, Mediterranean wrasse, branching Axinellae sponges, graceful fan worms; the majestic Alcyonium coral and an unusual creature that resembles the African baobab tree – the Ocnus planci sea cucumber.
